Apparatus and method for displaying image, and apparatus and method for driving light-emitting device

摘要

An apparatus and a method for displaying an image, and an apparatus and a method for driving a light-emitting device are provided. The apparatus includes: a transient state information provider which generates and outputs image data of an input image and a timing signal for displaying the image data on a screen, and provides a transient state signal in an abnormal operation of a power source or the image input into the apparatus; a display panel which receives the image data and the timing signal and displays the image on the screen by using the image data and the timing signal; and a backlight unit (BLU) which generates a control signal for controlling a light-emitting device providing light to the display panel and adjusts a characteristic of the control signal corresponding to an abnormal operation section of the abnormal operation to be linearly changed by using the transient state signal provided from the transient state information provider in order to control the light-emitting device.
